Answer:

Explanation:

Let the volume of the unknown bulb = X L

The volume of the system , after opening valve = (X + 0.72 L )

Use Boyles law gas equation,

P1V1 = P2V2 ( at temperature is constant )

Given:

P1 = 1.2 atm

P2 = 683 torr

Converting mmHg to atm,

1 atm = 760 mmHg(torr)

683 mmHg = 683/760

= 0.8987 atm

1.2X = 0.8987*(X + 0.720)

1.2X = 0.8987X + 0.6471

0.3013X = 0.6471

X = 2.15 L

A new roller coaster contains a loop-the-loop in which the car and rider are completely upside down. If the radius of the loop i
Oduvanchick [21]

To solve this problem it is necessary to apply the concepts based on Newton's second law and the Centripetal Force.

That is to say,

F_c = F_w

Where,

F_c =Centripetal Force

F_w =Weight Force

Expanding the terms we have to,

mg = \frac{mv^2}{r}

gr = v^2

v = \sqrt{gr}

Where,

r = Radius

g = Gravity

v = Velocity

Replacing with our values we have

v = \sqrt{(9.8)(11.8)}

v = 10.75m/s

Therefore the minimum speed must the car traverse the loop so that the rider does not fall out while upside down at the top is 10.75m/s
